The pressure monitoring assembly is attached to the distal port of a multilumen central vein catheter. The CVP catheter is an important tool used to assess right ventricular function and systemic fluid status.
The CVP catheter is also an important treatment tool which allows for:. Instant Feedback:. The A wave starts just after the P wave ends and represents the atrial contraction. The high point of the A wave is the atrial pressure at maximum contraction. During the A wave the atrial pressure is greater than the ventricular diastolic pressure. At that point, the atrium is contracted, the tricuspid is open. Therefore, the high point of the A wave closely parallels the right ventricular end diastolic pressure.
Central venous pressure CVP monitoring is used to assess the fluid status of patients in critical care settings. This article explains CVP monitoring, discussing the rationale for its use, the ways CVP can be measured, and the physiological factors that can affect the reliability and validity of CVP measurement. It also discusses the complications associated with CVP monitoring and the nursing responsibilities in relation to this activity. Nursing Standard.
